Platform Engineer

Every deployment. Every release. Every engineer. Your work will shape how software is delivered across Bigbank. Software engineers should spend their time building products - not managing infrastructure.

As a Platform Engineer, you'll build the internal platform that enables engineering teams to deliver software faster, safer and with greater confidence. With GitOps, Infrastructure as Code and CI/CD automation and developer experience, you'll help shape the tooling, standards and platform capabilities that engineering teams rely on every day. If you're excited about automation, modern platform engineering and solving complex technical challenges at scale, we'd love to meet you.

Join us to build the best universal bank! Bigbank is an Estonian bank with a strong international presence, operating across nine markets. We are expanding beyond lending into everyday banking, with the ambition to become a leading universal bank in our region. What makes this journey unique is the opportunity to build core banking services from the ground up using modern technologies and a next-generation platform - without the constraints of legacy systems. You'll join our Site Reliability Engineering team, where reliability, automation and developer experience are treated as core engineering priorities.

How do you create value?
You build the platform that every engineering team depends on. Your work removes friction from software delivery, improves reliability and enables developers to focus on building products instead of managing infrastructure.

In this role you will:

• Design and optimize platform infrastructure that powers Bigbank's services.
• Build and improve GitOps-based software delivery processes and platform automation.
• Investigate, troubleshoot and resolve platform and infrastructure issues in production.
• Improve the scalability, availability and operational efficiency of the platform.
• Help establish and evolve platform engineering practices across the organization.
• Manage the lifecycle of platform services and infrastructure components.
• Collaborate closely with Software Engineers, Site Reliability Engineers and Enterprise Architects by providing platform services, operational guidance and architectural recommendations.
• Maintain technical documentation that supports reliable operations and knowledge sharing.
• Contribute to service capacity planning, performance optimization and operational readiness.
• Participate in disaster recovery planning, testing and continuous improvement activities.
• Participate in the team's on-call rotation.

Tech you'll work with:

• GitLab
• Infrastructure as Code
• ArgoCD
• Helm
• Kubernetes
• Linux

• Think in platforms instead of individual solutions.
• Design infrastructure with automation, reliability and scalability in mind.
• Build CI/CD pipelines that make software delivery seamless.
• Advocate Infrastructure as Code and GitOps principles.
• Take ownership from investigation to implementation.
• Continuously improve the developer experience through better tooling and automation.
• Balance delivery speed with security, operational excellence and reliability.

Our expectations for you:
We believe you'll succeed in this role if you have:

• at least 3 years of experience in Platform Engineering, DevOps or Infrastructure Engineering.
• experience designing and operating GitOps-based software delivery in production.
• hands-on experience with Git-based workflows and GitLab CI/CD.
• experience with Infrastructure as Code and automation.
• experience managing infrastructure and application configuration through version-controlled workflows.
• strong troubleshooting and analytical skills.
• a collaborative mindset and willingness to improve engineering practices across teams.
• hands-on experience with Kubernetes, ArgoCD and Helm.

You'll stand out if you also have experience with:

• Cloud-native platforms
• Java or Node.js build pipelines

You'll probably enjoy this role if you...

• believe in platform delivery and infrastructure as code
• enjoy removing friction from software delivery
• like building solutions that other engineers rely on every day
• automate repetitive work before anyone asks
• prefer improving systems over maintaining manual processes
• enjoy solving engineering problems that have organization-wide impact
